For example, if the quantum numbers from Table 7.1 turn out to correspond to different types of superstring vibrations, then you shouldn’t think of these strings as fuzzy little objects with intrinsic properties like being made out of braided golden-brown cat hairs, but rather as purely mathematical constructs that physicists have dubbed “strings” simply to emphasize their one-dimensional nature and to make an analogy with something that feels less mathematical and more familiar.
